.IMPRovED CAR-BRAKE.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom, it may concern:

Be it known that I, ALBERT A. BLIVEN, of Jersey City, in the countyot'Hudson, and State of N ew J ersey, have invented a new and improvedCar-Brake; and I do hereby declare that thefollowing is a full, clear,and exact description-of the same, reference being had to theaccompanying drawings, forming a part of this specification, and inwhich- Figures 1 and 2 represent different views of acarbrake-coustructed according to my invention, taken at right angles toeach other.

Similar letters' of reference indicate parts in bot-h figures.

This invention consists in a novel construction ot' a railway-car brake,whereby el'iciency and great power are obtained, andV whereby thebraking of two carriages may be elfected at the same time by one man.

To enable others to understand the construction and operation of myinvention, I will proceed to describe it, with reference to thedrawings.'

.A is the platform of a railway-car, to the under side of which isbolted a frame, B B. 'lhis frame is constructed of east-iron or othermetal, and consists of a horizontal plate, B, and twodownwardly-extending lugs B.

C is a horizontal shaft, suspended within this frame, and carrying uponits central portion a ratchet-wheel, D.

Said ratchet-wheel D is provided with its teeth upon its sides, insteadot' its periphery, and is operated by means of pawls d d.

Said pawls d d are pivoted to the extended arms of' an inverted T-shapedlever, F, and their points held against the sides of the ratchet-wheelD, and between corresponding the teeth thereof, by means of bow-springss s, or other suitable spring-attaclnnent.

Tile inverted T-shaped lever F is pivoted, or linked at its lowerextremity, to the central portion of the front edge ot' the frame B B',by means ot'stapies c c', or other universal joint, so as to have aforward and backward, as well as a lateral motion.

The lateral motion of the, said lever F will, by the alternate action ofthe pawls d d against the teeth of the ratchet-wheel, cause the rotatingof the shaft C, while its forward and backward movement will cause,respectively, the engagement and disengagement ot' the said pawls andratchet, as illustrated by those parts of fig. 2 represented in redoutline.

Attached to the shaft C are chains li. h, which, passing forward andrearward, respectively, are connected wit-lithe shoes of the carriageupon which the apparatus is attached, and the one to which said carriageis coupled, so that the rotating ofthe shaft wili, by the winding up ofthe chains, cause the braking of the wheels of both carriages.

What I claim as my invention, and desire to have secured by LettersPatent, is-

The shaft O, ratchet D, pawls el d, and lever F, combined and applied toa railway-car, whereby the braking of the wheels of one or more cars maybe etleeted by the lateral movement-s of the lever, and the releasemeutot' the wheels by the tbrward movement of the same, substantially asdescribed.

ALBERT A. RLWEN.
